Broke a wire twice this past weekend, cost me a podium... I want some leadwire shrinkwrap!
 
I looked around and found 1/8" in 2:1 and 3:1 shrink... some had glue lining, too??
 
What size and kind of heat shrink do you guys use?

What are you using for leadwire, Charlie?

Usually before any big race I'll change out the leadwire just to be sure. That and I use either 18ga TQ leadwire or 18ga R/C wire. I dont think I've ever broken a leadwire in a race, but I've split a lot of leadwire clips in collisions.

As far as shrinkwrap, I have some I got from Del City electrical supply that I use. Covers down to 1/16" of an inch and just will go over 18ga leadwire.

Charlie, 

 

If you're using Kelly wire it's a dangerous thing! DZ and John Martin have found out how to use it. It requires some glue on the guide clips. The risk is not worth it to me!

Ditto. You have to strip the wire short. Solder it all the way towards the front of the clip. The jacket that sits on the clip you have to glue to the clip. That will keep it from bending at the solder joint and breaking.

No Kelly wire - yet...

 

NASCAR oval - wire broke due to rear ending someone in my way, took a perfect 1 mm high guide width chunk off the front edge of Kelly Daytona body. Also got a cut braid later on with someone in my way, Parma cut-down held up! Then broke same wire again w 12 seconds left, solder joint came unbuttoned - repair under green by rookie was not good enough. Would of, should of, could of... I won't ever forget to use paste flux and tin wire before trying to hurry a solder joint in a race...

 

My slot car laboratory still needs shrinkwrap - what size, and kind of shrink tubing?

Charlie,

 

If less than $13 plus a little shipping doesn't scare you off, consider this assortment from Del City. You'll never have to buy any more and I'll bet you'll find lots of other uses for it besides slot cars.

 

I bought a similar though smaller assortment many years ago and still grab a chunk for things every so often.

What I do, Charlie, works great, saves ~2 grams, and is stiffer than most all leadwire setups but not too stiff. I've used it for years now.

 

Kelly leadwire 24 gauge... I solder the wire the most forward on the clip... I use about 1" of shrink wrap. It's 1/16" diameter bought at most any electronic store in 3' lengths $2.

 

I cut the diameter In half about 1/4" inch back, see pic.
I smear that 1" of leadwire at the end with a two-part epoxy. Then slide the shrink wrap with the half cut diameter end over the soldered joint all the way forward on the clip. Then I add a small dot of the epoxy to the soldered joint and mash it down until the epoxy sets up, and a smaller dot to the top of the shrinkwrap to hold it even more.

Then a hair dryer will work to shrink the wrap.

Hey, Cheater - send me that drivers manual since you don't need it anymore. LOL.

 

I need more lap time - forced to work, eat, and sleep... the tide has started to come in.

Harbor Freight has a small variety pack of shrink wrap if you have a store nearby.

It's a lot nicer than my epoxy job .did you put a small amount on top of the clip and tubing, It's needed. Also I put end that runs to the clip on top of loop ,not under and a little bigger loop also ..they look really great and will give a much faster return to center ,helping get rid of any fishtail exiting corners..IMO.less drift in the curves.. Not to mention weight reduction ..

Thanks JC for this excellent training :good: ...yes, epoxied both inside the shrink tubing, and a drop on end so that the wire insulation just behind the solder joint is stuck to the clip, then the shrink covers it.  And now with wire to clip on top, the loop doesn't hit the sharp edge of the chassis where the wires run through.  Rookie Tip: use a very small amount of epoxy before sliding the shrink tubing down toward the clip, or you could epoxy the clip to the guide. :crazy:

Charlie epoxying the clip is not really that bad. It adds some strength.Even letting some get a little coverage on that thin outside edge of the guide next to the clip will strengthen that part as well. I added @ .50 thou to the outside edges from clip down to bottom of that weak portion.,( camera can't show it well.)Helping to maybe prevent it splitting.

That's lead tape LOL.
Tony P. Knows..LOL.
IMO thus far any lead wire larger dia. Than the armature wire is overkill..especially with so little amp. Draw.
Seems the bigger hate of the small wire is to keep it from breaking on the guide..I now got that covered ,,with a much better (quicker ) return to center on the guide ,= a tighter car..no wiggles off the corners..Oh yeah 2 grams less.. With Lead tape ..LOL

]Hog out all you want,,just be aware some tracks need more weight ..DZ cuts out everything then tunes with lead to different tracks as needed....works for him ...right. LOL
I'm trying to run a shorter car 3.75 . Shorter body ,=. 103 grams..I shortened this Arrow chassis. 1/4" off rear of pans .Then moved bracket forward 1/4" ..and cut the excess metals off the back ..It works great on the 3 tracks I've tryed it on. Love it..
